Can you turn NPC off, under "Manage Sheet"? As for the uneditable attributes, that is unfortunately an aspect of the Beacon Sheet. Nearly every attribute in the Attribute view is read-only, requiring you to use the actual sheet interface to make any changes. As for the number of NPC attributes, I believe this is normal. They exist whether they are used or not. The Beacon development environment is a wide departure from previous sheet architecture and does not fit traditional methods very well in many aspects.
